Desenvolvimento de um modelo numérico para simular o comportamento de conectores em chapa aplicados a pilares mistos preenchidos com concreto de seção esbelta (Development of a numerical model to simulate the behavior of plate shear connectors applied to

The cross-section of concrete-filled steel tube (CFST) columns is classified according to the local slenderness of the steel tube as slender, non-compact, or compact. There are analytical models to determine the axial force of locally slender CFST columns, however studies on load transfer from beams connected to these columns are scarce. This paper presents the process of the development and validation of a numerical model to simulate the behavior of Crestbond connectors applied to CFST columns with slender steel tubes, based on the results of experiments carried out. The numerical model presented can be used for the analysis and design of the load transfer in slender columns using connectors known as composite dowels.
